Polymer-assisted hydrothermal synthesis of trigonal selenium nanorod bundles

Uniform trigonal selenium (t-Se) nanorod bundles were synthesized by using Na2SeSO3 as reactant via a polymer-assisted hydrothermal method at 180 °C. The products were analyzed by using X-ray powder diffraction, scanning electron microscopy and Fourier transform infrared spectroscopy. The probable formation mechanism was discussed.
